7.3MASTER-SLAVE CONFIGURATION

SWITCHERS

[OUTmm]

This command sets the switcher to respond to specific output only. The default setting is output 1.

[SETxnnmm]

select input number

nn -

Minimum input number

mm- Maximum input number

This command is designed to allow the MX2406RM to program each input to respond to a selected range of input commands.

For example, if command [SET10104] is issued, then the following commands will select only Input

1:[I01O01], [I02O01], [I03O01], and [I04O01]. In other words a range of I/O commands can address the same input. The default settings for each of the inputs are as follows Input 10101, Input 20202, Input 30303, Input 40404, Input 50505, and Input 60606.

7.3MASTER-SLAVE CONFIGURATION

These feedback codes allow multiple MX2406RM Switchers to be connected in a Master-Slave configuration, if desired.

When the control ports of two units are connected as shown below, the slave unit duplicates the actions of the master unit. The same unit can still be controlled from its front panel or through another RS-232 control.

Master-Slave Analog Switch Voltage Connection

With this configuration the Master unit has ultimate control over slave unit.

7.4CONTACT CLOSURE (ONE WIRE ANALOG) CONTROL

The one wire control is an alternative to a multi- wire contact closure control. This control pin allows you to select different channels based on the DC voltage level on the pin 7 of the 9 pin D connector. Internally pin 7 is pooled up to 5 volts by 10k resistor. Thus, by selecting proper resistor values connected to ground any channel can be selected. Although the channel selection by relay contact is latching and will maintain the last relay-selected channel, it is recommended that momentary contact closures not be used. A typical resistor values and wires connections are shown below.

In some cases it may be preferable to use a seven- conductor wire to control the switcher with contact closures. The RC5204CC adapter is available to
